[Introduction]：The wireless intercommunication switch is a terminal device that uses LoRa modulation technology to achieve wireless remote transmission of switching values. It supports four digital inputs (DIs) for data acquisition and four relay outputs (DOs) for control. Operating in the 850.125-930.125 MHz frequency band, its core function is to enable remote synchronous control. It requires no wiring and is highly user-friendly, allowing users to quickly integrate it into their own systems. It accepts a DC input voltage of 8-28 V. It is coated with a conformal coating that is resistant to mildew, moisture, and salt spray.

LED indicator and button description
| port | LED indicator color | illustrate |
| PWR | Blue LED | Power indicator light, always on when powered on, off when no power |
| LINK | Yellow LED | 1 to many (including 1 to 1) - bidirectional (when the devices have the same number of channels): |
| l As long as one slave is successfully connected to the master, the LINK indicator of the master will be on; | ||
| After the slave device is successfully connected to the host device, the LINK indicator of the slave device will be on; | ||
| 1 to many - two-way (different number of channels, each channel of the host is independently controlled by the slave): the host LINK indicator flashes several times according to the number of devices connected (cycle 300ms, after flashing, it goes out for 1s, and then flashes again). For example: if 3 devices are connected, the LINK indicator flashes 3 times according to the cycle, then goes out for 1s and flashes again; | ||
| STATE (indicator light) | Blue LED | Host: The indicator light is always on; |
| Slave: indicator light flashes slowly; | ||
| Pairing: indicator light flashes quickly; | ||
| Not paired: the indicator light is off; | ||
| STATE (button) | White buttons | 1. Press and hold for 2 seconds to enter pairing mode; |
| 2. Press and hold for more than 6 seconds to restore to factory settings; | ||
| 3. Press and hold to cycle through the pairing state and reset state; | ||
| 5. In pairing mode, short press to exit pairing mode | ||
| DI1-DI8 | Green LED | Device switch input data indication, normally on means there is input, normally closed means there is no input |
| DO1-DO8 | Red LED | Each of the 8 relay output switch indicators corresponds to the 8 relay outputs; normally on indicates output is in progress, and normally closed indicates no output. |
